语源
late 18th cent. (originally dialect in the sense 'blow in puffs or small gusts', describing the wind): imitative. The current sense may have been influenced by dialect faffle 'stammer, stutter', later 'flap in the wind', which came to mean 'fuss, dither' at about the same time as faff (late 19th cent.)
